FOLDING- SHELF.

Specircation of Letters Patent.

Application led Deeember 11, 191'3. ISerial No. 805,908.y

To all whom t may concern Be it known that I, CHARLEs' A. Knssnen, acitizen of the United States, residing at Pittsburgh, in the county ofAllegheny and y State of Pennsylvania, have invented 'new and usefulImprovements in Folding Shelves, of which the following a. specifilcation.

My invention relates. to folding shelves,

designed especially for 'display stands forfruit or other objects. A

The object lof my invention -is tol provide display, stands or analogousstructures with folding or collapsible shelves.

y proved hingesforsuch shelves'or other fold` y 3 looking toward t Afurther object is to provide for such stands or structures suitablefolding supports. i

A still further-object is torprovide iming objects.

Referring to the accompanying drawings, Figure 1 is-a verticalcross-section of a folding stand embodying my invention; Fig. 2, a frontview thereof; Fig. 3, fan enlarged side view of one` of the hinges shownon Figs. 1 and 2; Fig. 4, an elevation of Fig.

of a second form of hinge;` Fig. 6, a side lview of a third form ofhinge; Fig. 7, a front view of Fig. 6; Fig. 8, a side vie'w of a fourthform of hinge, showing the parts in one'position; Fig. 9, a view of thehinge shown in Fig. 8 with the parts in a different position; and Fig.10, a side view'of a fifth form of hinge. y

On Figs. 1 and' 2, I' show a vertical rectangular frame having thevertical end members 1 and 2, connected together by the Y horizontalmembers 3 and 4. To .the front faces of the members 1 and 2 and near thelower ends thereof, I secure the U-shaped brackets 5, between the freeends of which I pivot the horizontal supports or braces 6, so

. that the latter can beswung out at right angles to the frame withtheir outer ends on the iioor, ground, or other surface on which theframe stands. The braces 6 may be swung so as to lie parallel with themember e left ;"Fig. 5,11 side view i web or ange 12 arranged at rightangles tothe base l1 and secured thereto by heading down the lugs 13projectingfrom the flange 4through holes in the base. The forward edgeof the fiange 12 is bent laterally at a rlght angle to the flange so asto form the front guide orI lug 14. The rear edge ofthe flange 12 nextto the base 1() is also bent opposite the lug 14 so as to form a reargulde or lug 115.1 'The lugs 14 and 15 lie on the same side of the webor flange 12. vThe hinge or member 8 comprises an angle piece of iron orsteel having the vertical member 16 secured to the bottom thereof. Theshelf 7 is secured to the angle piece by the screws 17. The member 16 isa flat piece of iron or Steel arranged parallel and in contact with theilangesor web 12 andfhaving the vertical slot 18 for the headed pin` 19which is secured in the web 12, the head of the pin lying over the outerface of the member 16. The lower end of the member 16 lies between thelugs 14 and 15, which guide the same and hold the shelf steady, the lug15 preventing the member 16 Afrom any tendency to pry the web 12 awayfrom the base 10. By raising the `member 8 and thereby causing themember 16 to travel up on the pin 19 until the lower end nf the slotengages the said pin, the member 8 may be swung downwardly on the pin 19as a center, the forward edge of the'member finally resting on the topof the lug 14 (dotted lines, Fig. 3), which preferably has its upper endbelow the pin 19 by a dlstance equal to the distance between the slot 18and the front edge of the member 16.

On Fig. 5, I show the base flange 12a in one piece. I omit the lug 15and have the member 16 engage the base directly. In the place of the lug14, I provide the headed pm 14l secured in the flange' 12a and having-its head overla ping the member 16. The operation will e readilyunderstood as it is the same as in Fig. 3. The member 8 is shown foldedin dotted lines.

On Figs. 6 andv 7, the parts are the same as on Fig. 5 except that theheaded pin has been replaced by the lug 14", which is practically thesame as the lug 14 in Fig. 3.

On Figs. 8 and 9, the base 10 and flange or web 12c'are substantially.as in Fig. 3, but the lug 14 and the pin 19 are replaced by the two pins20 and 21 arranged one vertically over the other and secured in thev1()a and thel llO flange or web 12l whichhas the two pins 22 and 23 inthe slots 24 and 25 in the memberA 16. The slots 24 and 251are drawnfrom radii having their center between the said pins so thatJ the slot211 occupies substantially. the upper left quadrant and the slotsubstantially the lower right quadrant of a circle drawn from the saidcenter. The lower endl of the slot 24 and the upper end of the slot25have the horizontal' extensions 2G and 27, respectively, both extendingforwardly or away' from thebase 10d. Normally the pins 22 and 23 rest inthe /extensions 26 and 27. By pulling the member 8 forwardly or to theleft,-the` arc-shaped slots 24 and 25 arewbrought into registry with thepins 22, and 23, whereupon the member, 8 may be rotated to the dottedposition.

I claim- In a folding stand, a frame, a shelf therefor, and a hingeconnecting the frame and the shelf, one member of the hinge beingSecured tothe frame and comprisinga base,

a vertical flange thereon extending at a' right angle to the base andprovided with two projections at right angles thereto, the second memberof the hinge comprising a horizontal portion secured to vthe shelfand avertical portion secured to the horizontal portion and provided with atleastone slot CHARLES A.
